问题
I'm trying the 23.2 release Cocoa Emacs build (OS X 10.6). There's a number of things that are more annoying about Cocoa Emacs than the terrific Carbon Emacs (based on an Emacs 22 build, I believe), so I hoped folks might have some solutions/thoughts (unfortunately posting on neither the carbon-emacs list nor emacs-dev has produced a useful reply, so I thought I'd try Stack Overflow for the first time):
In Firefox, I can set the Preferences, Applications, mailto content type to "Use Emacs". This used to work in Carbon Emacs. Now when I click on a Firefox mailto link, it changes focus to Emacs but doesn't actually do anything.
My .emacs has the following, which I guess doesn't work in 23. Suggestions?
(setq browse-url-browser-function
'(("^http:" . browse-url-generic)
("^https:" . browse-url-generic)
("^mailto:" lambda (url &rest stuff) (compose-mail
(substring to 7)))
;; ("^mailto:" . browse-url-mail) ;; same behavior
("^file:.*\\.html?$" . w3m-browse-url))
)
回答1:
I suspect that emacs is failing to find the 'file' it's being told to open. Try a couple things on the command line to see what happens:
emacs mailto:example@example.com
should just open emacs and stare at you blankly.
emacs --eval '(browse-url "mailto:user@example.com")'
should handle the url.
If that all checks out, then you need to wrap things when firefox makes it's invocation (with a script unless FF lets you specify the command line using a %s replacement). Alternatively, you might be able to get things working by setting TRAMP up to understand a mailto: url, but that seems a bit convoluted.
(now that I know what to look for: you might find the EmacsWiki:MailtoHandler helpful.)
